Physical Kinetics of Ferroelectric Hysteresis

The physical kinetics of single domain ferroelectric materials are studied using Landau-Khalatnikov equation. The hysteretic curves are obtained numerically. The effective coercive electric field theoretically varies with the driving amplitude and frequency. The effects of thermal noise are explored using the Fokker-Planck kinetic equation. The ferroelectric switching times are discussed and Quantum effects are briefly explored.
